Title
Does Rubus canadensis Interfere with the Growth of Fraser Fir Seedlings
Eric F. Pauley 1989
Other claims from this paper (13)
- Observation Rubus canadensis density was highest on the southwest-facing slope.
- Observation Fraser fir seedling density was highest on the northeast-facing slope.
- Association In most years terminal shoot growth of fir seedlings was positively associated with Rubus density (coefficients 0.309 to 0.396, P < 0.01).
- Association Rubus density and biomass were significantly correlated with soil phosphorus and potassium concentrations.
- Association In all measured years, terminal shoot growth of fir seedlings was positively associated with soil pH and potassium concentration.
- Observation Only 38% of the fir seedlings were younger than 5 years.
- Observation More fir seedlings than expected occupied dead wood substrates.
- Observation More than 25% of seedlings showed adelgid damage.
- Observation Most seedlings showed a trend of increasing gains in terminal shoot growth over previous years.
- Intervention effect Removal of Rubus stems had no significant effect on fir seedling shoot growth over one season.
- Observation Rubus responded to stem removal by rapid appearance and growth of new stems.
- Intervention effect Large seasonal changes in bryophyte cover and red spruce seedling density occurred and were not affected by Rubus removal.
- Association Fir shoot growth does not appear to be associated with Rubus density or biomass.
